急性心肌梗死患者碎裂QRS波的临床分析
Fragmented QRS Complex in Acute Myocardial Infarction Patients
摘要
Abstract
Objective To explore the value of fragmented QRS complex in the diagnosis of acute myocardial infarction ( AMI ). Methods Incidence rates of fQRS among AMI patients and coronary arteriography ( CAG ) negative patients were compared; incidence rates of fORS and Q - wave among ST - segment elevation myocardial infarction ( STEMI ) patients and non - ST-segment elevation myocardial infarction (NSTEMI) patients, were compared. Further, incidence rates of arrhythmia, reoccur angina pectoris, decline in LVEF ( ≤40％ ), cardiac shoc:k and cardiac death of patients with and without fQRS were compared. Results Incidence rate of fQRS is higher among AMl patients ( 36 cases, 22.22％ ) than among CAG negative patients ( 8 cases, 4.94％ ) ( X2 =20.618, P＜0.05 ). In the cases of NSTEMI, fQRS is more frequently ohserved than Q-wave (P＜0.05 ). Incidence rates of arrhythmia, re - occur angina pectoris, decline in LVEF, and cardiac death among patients with fQRS are significantly higher than those of fQRS - free patients ( P ＜ 0.05 ). Conclusion FQRS could serve as a new indicator in the diagnosis of AMI, especially for cases of non - Q - wave myocardial infarction or NSTEMI. It can also considered as one of the early indicators for AMI severity.关键词
